摘要

遠距復健為近年來全新的復健領域，藉由醫療與工程的結合，對於醫療資源不發達的地方或者因為病患失能造成的就醫不便，提供全新的復健治療方式。本研究針對膝關節處，利用微機電(MEMS，Ｍicro-electro-mechanical system)之慣性感測器(IMU，Inertial Measurement Unit)開發一微型遠距復健裝置(Telerehabilitation device)，並設計出一遠距復健整合之系統去量測觀察復健之相關成效以及研討遠距復健之可行性。預計先以膝關節置換術(TKR，Total knee replacement)的術後病患以及肌肉無力(Muscle weakness)之病患為收集之主要目標，收集之動作方面為單純膝關節活動，作為後續分析的先遣研究。研究中提出之微型遠距復健系統將有助於減輕病患在復健時的負擔、降低治療師的勞力付出、減少病患往來醫院的不便，並達到居家復健照顧與病情追蹤的目的。
首先，經由國泰綜合醫院的共同研究之下，藉由醫師與研究對象溝通並向其說明研究的目的以及相關之流程，並在受測者有自主判定之情況下取得受測者同意書；隨後，將非侵入式感測器綁至於腳踝外側，並請研究對象執行相關復健行為。經由慣性感測器將人體執行復健之波動讀取收集後，將受測者以及正常人做為比對，希望藉由程式的判定並評估病患在主動式以及被動式的復健情況下之復健情形，並對其復健狀況來探討遠距復健之成效。

Telerehabilitation is a new field of the rehabilitation in recent years. Through the combination of rehabilitation medicine and engineering, a new way to provide patients with rehabilitation is available now.
In this study, we used inertial sensors to design a miniature telerehabilitation equipment, which was able to detect the motion of knee joint and further to design a telerehabilitation system for measuring and following the effectiveness of rehabilitation program. The telerehabilitation system was made as a Graphical User Interface(GUI), which make the observers more easily to monitor the effectiveness of rehabilitation. We used Fast Fourier Transform(FFT) and prototype wave to analyze all the motions. Finally , we discussed the feasibility of IMU as the sensors of telerehabilitation.
This research is in collaboration with Cathay General Hospital. All informed contents were obtained before participants receiving tests. Then, we choice the patients who would receive total knee replacement and patients with muscle weakness due to brain injury.
In this study, we proposed IMU is a potential tool for the telerehabilitation. It could be reliable, to save time and reduce the cost of rehabilitation and reduce the burden of clinical health providers. Compared with traditional telerehabilitation sensors, IMU seems more convenient, reliable and useful..
